Emergency Contraceptive Pill: How It Works and When to Take It
In this blog, we will understand how emergency contraception works and when it should be taken.
What Is Emergency Contraception?
Emergency contraception is a safe and effective method used to prevent pregnancy after unprotected intercourse. It is not a substitute for regular contraceptives, nor is it an abortion pill. Its role is to reduce the chances of pregnancy by interfering with the fertilisation or implantation process.
Morning After Pill vs Emergency Contraceptive Pills
The morning-after pill is a type of emergency contraceptive pill, available over the counter in most UK pharmacies. Some morning-after pills remain effective up to five days after unprotected sex.
Unlike daily oral contraceptives or contraceptive implants, emergency pills are used occasionally and do not offer long-term protection. They are a safety net, not a routine method of contraception.
How Does the Emergency Contraceptive Pill Work?
Emergency contraceptive pills primarily work by delaying ovulation, preventing the release of an egg during the fertile window. Some formulations may also alter the uterine lining, reducing the likelihood of implantation.
Common Ingredients and Mechanism of Action
In the UK, the two main types of emergency pills are levonorgestrel and ulipristal acetate. These hormones interfere with the natural cycle to prevent pregnancy.
How Timing Affects Effectiveness
Emergency contraception should be taken as soon as possible after unprotected sex. It is most effective within the first 3 to 5 days. Levonorgestrel-based pills work best within 72 hours, while ulipristal acetate remains effective for up to 120 hours (five days). The sooner it is taken, the better the outcome.
Other Types of Contraception to Consider
While emergency contraception is a vital option in urgent situations, it should not be relied upon as a regular method of birth control. Long-term options offer more consistent and effective protection, which include:
Long-Term Options vs Emergency Use
Methods such as the contraceptive implant, intrauterine devices (IUDs), patches, vaginal rings, and daily oral pills are designed for ongoing use. They reduce the chances of contraceptive failure and provide greater peace of mind compared to emergency pills.
If you're unsure which method suits you best, speak with a pharmacist or a healthcare provider. They can assess your medical history, lifestyle, and preferences to help you choose the most suitable form of contraception.
